spectral emmision lines looking for list plus info..tia sal

I'm looking for a list of spectral emmision lines for all the elements is
there a book or website that shows this? I would also like to know if
there is a way to convert the spectral emmision lines from the elements
into it's corresponding wavelenght?

Example if the spectral emmision line red shows up how can I convert this
to it's proper wavelength value and its intensity? 700NM - 785NM? Has this
been done already? If so can you point me to it?
